Abstract
A device for controlling a working machine has at least two control levers which are each operatively connected to at least one control device via an actuation unit. The actuation unit comprises a switching device with which the assignment between control levers and control devices is interchangeable. The switching device comprises at least four levers, of which every two levers are assigned to a control lever. Each of the four levers has a stop point for an actuation element. Each actuation element engages on the stop point with the respective assigned lever via couplings that can be detached without tools.
Claims6
A device for controlling a working machine comprising:
- first and second control levers that are each operatively connected, via an actuation unit, to at least one respective control device, the actuation unit including a switching device with which the assignment between the control levers and the control devices can be interchanged, the switching device having at least four levers, of which two levers are assigned to each control lever, and each of the two levers that is assigned to each associated control lever is immediately connected, via a first pendulum support, to the associated control device, and wherein each of the levers that is assigned to one of the associated control levers and that is immediately connected to one of the control devices is capable of being pivoted synchronously with another of the levers that is connected indirectly to the control device that is assigned to the other of the first and second control levers,
- wherein each of the two levers that is assigned to each of the first and second control levers has an attachment point for engaging a first end of an actuating element assigned to the respective one of the first and second control levers, each said actuating element engaging at a second end thereof on the associated control lever, and wherein the first end of each of the actuating elements engages the attachment point on the respectively assigned lever via couplings that can be detached without the use of a tool.
A device for controlling a working machine comprising:
- first and second control levers;
- first and second control devices;
- an actuating unit that connects the first and second control levers to the first and second control devices, the actuation unit including a switching device switchable between 1) a first state in which the first control lever is connected to the first control device and the second control lever is connected to the second control device and 2) a second state in which the first control lever is connected to the second control device and the second control lever is connected to the first control device, the switching device having first and second levers assigned to the first control lever and third and fourth levers assigned to the second control lever,
- wherein the first and second levers are immediately connected to the first control device by a first pendulum support and the third and fourth levers are immediately connected to the second control device by a second pendulum support,
- wherein each of the first and second levers is capable of being pivoted synchronously with at least one of the third and fourth levers,
- and further comprising 1) a first actuating element having a first end that is connected to the first control lever and a second end that is associated with the first and second levers and 2) a second actuating element having a first end that is connected to the second control lever and a second end that is associated with the third and fourth levers,
- and wherein each of the first, second, third, and fourth levers has an attachment point that engages the second end of the associated actuating element via at least one coupling that can be detached without the use of a tool.
